Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12000, here are decompositions:
- 13 + 11987 = 12000
- 19 + 11981 = 12000
- 29 + 11971 = 12000
- 31 + 11969 = 12000
- 41 + 11959 = 12000
- 47 + 11953 = 12000
- 59 + 11941 = 12000
- 61 + 11939 = 12000
Showing the first eight; more decompositions exist.
